Sustainable Village - Better Ways to WaterRegenerative Agriculture Since 1971 - Free Quotes & Consulting - Cutting Edge Products & Systems - Customized Engineering DescriptionDeveloped to easily extract soil water samples for testing. They provide the user with an accurate method of determining salinity or plant nutrient levels. Because the sample is collected at root zone depth, it reflects the true impact fertilization has on the plant material. Understanding soil water conditions helps the user make informed fertigation scheduling decisions resulting in improved yield and reduced fertilizer, water, labor and energy costs. Features: • Easy to install and use • Standard ceramic tip (white) for most soil types • Low Tension tip (blue) for sandy soils and growing media • Optional Double Suction line for longer tubes • Collects soil water sample at the root zone OPERATING PRINCIPLE: The SSAT shares a few construction features with the very popular IRROMETER instrument which measures soil water tension. The SSAT consists of a sealed plastic tube that is equipped with a porous ceramic tip on the bottom end. The tube is installed in the ground with the ceramic tip placed at desired root zone depths. After an irrigation / fertigation event, a slight vacuum is applied to the tube which has a suction line extending past the top seal and a valve to seal it off. The vacuum in the tube draws soil water through the porous ceramic tip where it accumulates in the tube. To collect the sample from the tube the operator simply connects a syringe to the suction line, opens the valve and draws it out. When using the double suction line option, pressurize the tube to push the sample out. The sample can then be analyzed in the field or at the laboratory. This soil nutrient information helps the user make informed fertilization decisions. APPLICATIONS: Crop consultants, irrigation professionals and researchers find the SSAT particularly useful because of its ability to easily gather soil water samples for testing. Commercial growers see the value of soil water sampling at the root zone because it reflects the net “effect” that fertilization has as it interacts with previously applied nutrients in the soil. Scientists also use this equipment when identifying and researching environmental contaminants and their movement in soil. SPECIFICATION INFORMATION: The operator shall incorporate soil water sampling equipment to aid in making fertilization scheduling decisions. The soil solution access tubes shall collect samples at the root zone for analysis in the field or laboratory. Tube shall be constructed of durable plastic that is impervious to attack by soil chemicals, with a ceramic tip. All ceramic to plastic connections shall be guaranteed leak proof. The soil sampling device shall be a Model SSAT as manufactured by the IRROMETER Company, Inc. of Riverside, California.
